Mary has a cone that has a radius of 5cm and height of 10cm. James has a square pyramid with base length of 10cm and height of 5

lukranit [14]

Answer: The cone has a larger volume.

Step-by-step explanation:

Volume of a cone = ⅓πr²h

where, radius = 5cm

height = 10cm

Volume = ⅓ × 3.142 × 5² × 10

Volume of cone = 261.83cm³

Volume of square pyramid = A(h/3)

where, A = 10 × 10 = 100cm²

Volume = 100 × (5/3)

Volume of square pyramid = 166.67cm³

Therefore, the cone has a larger volume.

Dory and nemo go to Taco Bell for lunch.dory orders three soft tacos and three double deckers for $11.25 nemo pays $10.00 for fo

Maslowich

If we let x be the price for soft tacos and y be that of double deckers, then from the question, we'll have 3x + 3y = 11.25 x + y = 11.25/3 x + y = 3.75 (1) in addtion, we also have 4x + 2y = 10.00 2x + y = 5.00 y = 5.00 - 2x (2) <span>Substituting y from equation (2) into equation (1), x + (5.00 - 2x) = 3.75 -x = 3.75 - 5.00 x = 1.25 y = 5.00 - 2(1.25) = 2.50 </span>

what information do you need to create a cylinder, a sphere, and a pyramid that all have the same volume?

NNADVOKAT [17]

Answer:

h=4/3 r Base area =27(pi)/16 h^2

Step-by-step explanation:

The Volume of the following solids are

Cylinder: (pi)r^2 h

Sphere:4/3 (pi) r^3

Pyramid: 1/3(base area) h

Assuming that the Volume is the same in all three solids

(pi)r^2 h= 4/3 (pi) r^3

Simplify

h=4/3 r

(pi) r^2 h= 1/3(Base area)h

Simplify

(pi) r^2= 1/3 base area

substitute r=3/4 h

(pi) 9/16 h^2=1/3 base area

Base area =27(pi)/16 h^2

Answer:

(b) y = -5x

Step-by-step explanation:

When "y varies directly as x" the equation for that is ...

y = kx . . . . . . . for some constant k

The value of k can be found by solving for it:

k = y/x . . . . . . divide by x

So, the given point (x, y) = (2, -10) tells you the value of k is ...

k = -10/2 = -5

and the direct variation equation is ...

y = -5x

_____

<em>Additional comments</em>

There are a couple of other useful facts about direct variation. When you compare the equation to the slope-intercept form equation for a line, ...

y = mx + b

you see that b=0 and the slope, or rate of change, (m) is the same as k.

The y-intercept of 0 means that the graph of any direct-variation equation must go through the origin. (If it does not, then the variation is not direct.)
